PISTOL.

Specification of Letters Patent.

Application "filed December 15, 1911. Serial No. 665,977.

- ing is a specification.

My invention relates to a self-loading pistol, a so-called recoil loader, comprising a stationary barrel and a breech guided on the stock, and a primary object is to provide an improved pistol of the type described comprising a breech guided in an improved manner, and improved trigger mechanism.

One illustrative embodiment of the invention is represented by way of example in the accompanying drawing, wherein;

Figure 1 shows my improved pistol partly in side elevation and partly in longitudinal section; Fig. 2 is a top plan view thereof,

only the fore end of the breech being shown,

Fig. 3 a rear, elevation and F ig. 4 a front elevation; Fig. 5 is a side elevation showing the breech lifted, Fig. 6 is a longitudinal section through the rear portion ofthe pistol, and Fig. 7 a like view showing a safety device for the hammer and its catch.

The butt or stock 1 of the pistol, to which the barrel 2 is immovably attached, .is formed as a guide for the breech 3. To this end, the fore end 4, to which the triggerguard 5 is attached, has a rectilinear guiding face 6 on whichthe breech 3, preferably provided with somewhat overlapping-edges 7 (Fig. 4), can slide. For guiding the member 3 on the stock 1 I provide on the rear end of the latter lugs or projections 8 which enter into corresponding grooves 9 (Fig. 5)

in the breech 3. Each of the grooves 9 runs out atits inner end into a transverse groove 10, the purpose of these grooves 10 being to enable the lugs 8. to be removed from the grooves 9 when the weapon is beingdismembered.

The breech 3 surrounds the barrel on all sides but without contacting. wi,th it, and between the breech and the barrel is disposed the closing spring 11. This spring .is tensioned between a sleeve 12,'which closely surrounds the front end of the barrel and serves as a short casing therefor, and a rear sleeve 13. In the illustrative embodiment the former sleeve is attached to the breech 3 by means of a bayonet-joint constituted by a rectangular incision 14. cut in the sleeve 12 and a' lug or projection 15 on the breech 3.

The casing 12 of the barrel may, if'preferred, be screwed into the breech Patented Apr. 22, 1913.

' A shoulder 16, which is preferably at least front of the transverse grooves 10 at the place designated a in Fig. 5.

When it is wished to dismember the weapon, the sleeve 12 looking the breech at the front end must first be rotated until its bayonet-joint is detached, whereupon the sleeve 12 jumps out under the action of the spring 11 and this spring andjthe sleeve 13 can be removed. The breech is then pulled back so far while simultaneously lifting it from the face 6 and the shoulder 16 that the lugs 8 pass into the transverse grooves 10, whereupon the rear end of the breech can be lifted and removed from the barrel toward the front (Fig. When assembling the weapon the operations are carried out reversely. With regard to the arrangement of the lugs 8 and the grooves 9 and 10 on or in the stock and breech it may of course be vice versa.

The breech 3 has a. lateral aperture 17 through which are ejected the empty cartridge cases pushed to one side by the projection 18 (Fig; 2) on the stock.

The trigger mechanism comprises the finger or trigger 20, the rod 21 able to be shifted longitudinally by the same, the hammer or cook 23 fulcrumed at' 22, and the safety-catch 24 inserted behind bot-h the hammer and the rod 21. This catch, pivotally mounted at 25, is located laterallyv of the hammer but so, however, that whenthe hammer is tensioned the recessed shoulder 26 of the catch clasps a projection 27 on the sioned by the spring 28, while its lug 26 c0- acts with the rod 21. The catch is held pressed by a spring 30 against the hammer and the rod 21, while the latter is pressed by a spring 31 against the catch.

As will be readily understood, my proved trigger mechanism principally dif- .fers from 'known constructions in that the.

catch '24 is arranged laterally of. the hammer and the same plane with the rod 21.

hammer and thereby holds the hammer ten- 7 knother feature of importance is the pivvting of the catch 24 at its lower end at a mint behind the hammer, thereby obtaining greater length and a greater stroke than f the latch were arranged in front of the iaminer. In consequence of this arrangenent a relatively light pressure on the trigger 2O sufiices to move backward the shouller 26 from the projection 27 of the hamrier by means of the rod 21 coacting with he lug 29 of the catch 24, whereupon the lammer flies forward under the action of ts spring 28 and impacts against the firingin 32 for discharging the weapon. Apart rom the saving in power, the improved orm and arrangement of the safety-catch 4 has the advantage that neither does the weapon require to be lengthened rearwardly LOI' need the stock be provided below with vrojections which inconvenience the han- Lling of the weapon.

The hammer can be locked in the usual aanner by a rotary lock which comprises a bait 34 of non-circular cross-section rotaable by a crank-handle 33 and engaging a a recess 35 in the hammer. In the form ccording to Fig. 7 this shaft 34 simultaneously serves for locking the catch 24. The

latter has an arm 36 which when. locked bears against the part 37 of the shaft 34, while the hammer is secured by the part 38 of the shaft 34 engaging in its recess 35.

I claim In a pistol of the character described comprising a stock, a fixedly mounted barrel, and a breech guided between the barrel and the stock, the combination of the trigger, a rod having one end pivotally attached to the latter, a spring-pressed hammer ivotally mounted on the stock in the breech, and a catch normally engaging the hammer and coacting with the other end of the said rod said catch bein located in the rear of said rod and also being pivoted at its lower end in the rear of said hammer, said catch being adapted to be disengaged from the hammer by the, rod.

In, testimony-whereof, I afiix my signature in the presence of two witnesses.
